IWC Ceralume Pilot's Watch Prototype
Most watch collectors are familiar with Super-LumiNova, used to make indexes and hands visible at night. IWC used their pigments in a mix of ceramic to produce the Ceralume case of this Pilot's Watch prototype. As the above suggests, the 41mm case of the watch glows after dark, as do the dial and hands. Purely a proof-of-concept build, IWC says the Ceralume material will be incorporated into future production models.
